APPARATUS FOR TREATING PAPER CUPS THE LIKE.

Application led January 27, 1922. Serial No. 532,181.

'I he invention relates to improved apparatus, for treating paper cupsand the like receptacles and is especially useful for treatingindividual paper cups with a water proofing material. In my application,fimpregnated paper or like receptacle and method of making same SerialNo. 526,259, filed December 31, 1921. I have described a cup which isimpregnated with a water proofing material which will not give anappreciable odor or taste when put to the lips, which will not have anappreciable coating of the indurating material thereon, particularly onits outer surface, and which will have other advantageous features, thesaid application also describing an improved method of making such cups.The present invention has to do. articularly with a form of apparatus bywhich cups ofthe character referred to may be effectively treated orimpregnated with water proofing material in the manner referred to insaid application.

In accordance with the present invention apparatus is provided wherebythe impregnating or treating material in the form of a molten'liquidisapplied to the inside of the cup and is then emptied therefrom, themethod of proceeding being such that there will be substantially nocoatin on the outside of the cup when finishe This may be accomplishedby pouring a comparatively small amount of the hot fluid into each cupand then emptying the same therefrom and atthe same time imparting sucha movement to the cup, or imparting such a relative movement to the cupand the fluid therein, as to cause the fluid to flow spirally over theinner surface of the cup, as it flows therefrom, or, generally, to flow`in such a manner as to cause the liquid to touch upon separated portionsonly of the cup, extendingl from the bottom to the rim. The cup is thenheated to spread the impregnating material, deposited on said separatedareas, over the remaining .inner surface of the cup.

An object of the present invention is the provision of improvedapparatus whereby a process of the character referred to may becarried-out in an effective manner. In the preferred form of apparatusmeasured quantities of hot impregnated fluid Vare automatically pouredintov the cups' whi h are.

then automatically emptied and at the same time given such movements asto cause the desired distribution of the fluid over the inner surfacesof the cupsv as the same are emptied, after which the cups areautomatically ejected from the cup holding means and carried through anoven whereby the separated liquid material on the inner surface of thecup will be caused to run and spread by capillary-attraction over theentire surface. 'Further objects and advantages of the invention willmore fully appear from the following description taken in connectionwith theaccompanying drawings illustrating one form of apparatusembodying the invention.

Referring to the drawings, Fig. 1 is 'a side elevation of a form of anapparatus embodying the invention;

Fig. 2 is a partial side-elevation of the same on an enlarged scale;

Fig. 3 is a topv plan view of the apparatus;

Fig. 4 is a vertical section taken on line 4 4 of Fig. 3;

Fig. 5 is a vertical section taken on line 5 5 of Fig. 2;

Fig. 6 is a vertical section taken on line 6 6 of Fig. 5, and

Fig. 7 is an enlargedvertical section taken on line 7 7 of Fig. 4.

Referring to the drawings, a frame work may be employed comprisingupright members 1, 1, and horizontal members 2, 2, supported thereby,form of channel irons, and which may be suitably secured together.

A table or support 3 is rotated step by step and carries a plurality o'fcup holders '4 in which the paper cups 5 which are to be treated may becarried. Table'3 is secured to a verticall spindle 6 which is rotatedstep by step from the shaft 7, the latter being shown as provided withbeveled gear 8 meshing with a beveled'gear 9 on spindle 6. Preferably asupport 1() extends across the horizontal members 2, 2, to which it maybe secured by bolts 11, this support having a sleeve 12 formed integraltherewith or secured thereto and extending upwardly therefrom, throughwhich spindle 6 extends. Table 3 is shown as being formed with adownwardly extending boss 13 which is which preferably take the pinnedto spindle 6 and which is'rotatably 4supported on a bearing 14: at theupper end of sleeve 12. v l

It may be well at this point to describe briefiy the various operationswhich are carried out by the machine. The table 3` carries a plurality,such as six, of the cup holders 4, evenly distributed around itsperiphery. If the table be considered as rotating in acounter/'clockwise direction, as is indicated in Fig. 3, operatives mayposition cups in the holders 4 at any of the three lefthand positionsindicated at a, b, and c, in Fig. 3. The cups illustrated are conicalpaper cups and the holders 4 are correspondingly tapered, the cupsfitting fairly closely therein so that they will be held therein byfriction.

In the operation of the preferred machine, when a cup holder advancesfrom the position indicated at c to the neXt position indicated in Fig.3 at d, the desired quantity of hot molten impregnating material such asparafine and waXor the like will be poured therein, this preferablybeing an automatic operation. During the neXtstep forward of the table3, the cup holder positioned at d will be swung vertically through anangle of 180O so that the liquid therein will be emptied, the cup beingupside down when it arrives at the position e. During this tilting overof the cup holder, the cup holder and the cup therein will be rotatedabout its own axis through a suitable angle which may be from one-half arevolution to a full revolution. This causes the liquid in the cup toflow over the inner surface thereof in a spiral like path from thebottom towards the rim so that the melted paraftine and wax will bedistributed over separated portions of the inner surface of the cupalong lines which are generally spiral, the surplus liquid running outover the rim of the cup and being caught in a suitable colj lectingvessel.

As the cup and the cup holder reach the position indicated at e the cupwill be auto` matically ejected or separated from the cup holder andcaught by a suitable support, upside down, and carried olf, to Atheright, referring to Fig, 3, through a suitable oven in which the heat issuflicie-nt to cause the spreading of the impregnating liquid over theentire surface of the cup so as to sufticiently coat and impregnate t/hesame, the quantity of impregnating material being` sufHciently small sothat there Will be substantially noapparent coating on the outer surfaceof the cup andso that there will be little pr no apparent coating on theinside of the cup, while at the same time theshell of the cup isthoroughly impregnated.` As a result of this treatment, when a waterproof ing material of relatively high melting point is used, the cupwill withstand hot liquids at a temperature of about 170 F., and willhave other advantageous properties. The cups will be carried insuccession by a suitable conveyor through the oven and afterwards may becooled and stacked.

vAfter the cup has'been removed from the cup holder, in the positionindicated at e, the cup holder will be returned to its normal uprightposition, this operation preferably taking place during the next stepforward of table 3, while the cup holder is travelling from the positionindicated at e, to the position indicated at f.

Referring' now to the details of the apparatus illustrated,'the table 3as stated, is given -a step by step advance by connection with shaft 7which shaft is illustrated as supported in bearings 15, 15, which may behung from the clhannel shapes 2 lof the frame, and by a bearing 151suspended from the cross member 10.

Power for operating the machine may be taken from the motor or othersource of' power indicated at 16, which drives shaft 17 by a belt 18running over a sheave 19 on shaft 17. A parallel shaft 20 is rotatedfrom shaft 17 by suitable connections such as the pinion 21 and gear 22.A heart shaped cam 23 on shaft 2O is utilized to give an intermittentforward motion to the parallel shaft 7 previously referred to, by whichtable 3 is given its step by'step advance.

In the form of device illustrated an arm 25 on shaft 7 carries a pawl 26which is adapted to coact with a ratchet wheel 27 on shaft 7, thisratchet wheel having six teeth, when, as in the case illustrated, table3 is intended to be advanced one-sixth of a revolution each step. Pawl26,r4 may be spring pressed into engagement with the peripheryoforatchet wheel 27 by a spring 28 connected between the tail of pawl 26and an extension of the arm 25. An arm 29'is pivotally connected to theopposite end of 'arm 25 and carries a roller 30 which operates in thegroove of heart shaped cam 23, so that ratchet wheel 27 will be advancedone step for each revolution of cam 23. Lever 29 may be provided withbifurcated arms 31 which straddle shaft 20 so as to guide arm 2-9in itsforward and back movements. Shaft 20 issupported from the frame work bysuitable bearings, 93.

Each cup 5 receives the desired charge of molten material when it hasreached the position indicated at d in Fig. 3, preferably by mounted ontrunnions 'as illustrated at 46 to a bracket 43 secured to the frame 39.A flexible connection 44 leadsV from tank 38 into the rear end of ladle41, this connecting with tank 38 below the liquid level therein, so thatwhen the ladle 41 is in its horizontal position liquid will flow throughconnection 44 and fill ladle 41 uniformly to the same level, apre-determined quantity of liquid accordingly fiowing into ladle 41 eachoperation. An arm 45 is ivotally connected at its outer end to bracket43 at one of the trunnions 46, an intermediate pointon this arm beingpivotally connected to ladle 41 at the point 42. Arm 45 is pivotallyconnected at its rear end to a link 47. Link .47 is operated byconnection with shaft 2() preferably by providing the lower end of link47 with a roller which coacts with cam 48 secured to shaft 20. Ladle 41is provided at its forward end with a spout or pouring opening 49through which the molten charge in ladle 41 will flow into the cupscontained in cup holders 4 as the latter successively come intoalignment with the ladle at the position al, as shown in Fig. 3.

Cam 48 may be..so constructed as to hold ladle 41'-stationary, inhorizontal position, for a short period of time while the ladle fills tothe same level as that of the fluid in tank 38, a measured quantity ofliquid accordingly being contained in ladle 41. As soon as this isaccomplished link 47 will be raised by cam 48 to pour the charge ofmaterial contained in ladle 41 into the cup 5 aligned therewith, afterwhich the ladle is again returned to horizontal position and againreceives its charge of fluid material. Cani 48 makes one completerevolution during each forward and back movement of the arm 29, thetiming of this device being such that a ladle 41 will empty itself intoa cup 5 while the table 3ds stationary, that is while pawl 26 whichadvances the table is making its back stroke, ladle 41 thbn beingreturned to horizontal position, and being again filled while the tableis being advanced one space by pawl 26. No valves. are used in thepreferred device, whereby simplicity and efficiency are enhanced. Theflow of fluid to the ladle may be cut ofi' during each operation ofpouring from the ladle, by the fact that flexible' connection 44 may beraisedA above the fluid level in tank 38Aby the upward tilting oftherear end of the ladle.

Adjustment for filling ladle 41 to different levels may readily be madein various ways, as by making the height of pivots 42 of the leveladjustable. This may readily be accomplished by securing bracket 43 tothe frame 39 by means of bolts 49 which may extend through verticalslots (not shown) in v fra-me 39. lVhen this is done the link 47 willalso, of course, have to be made adjustable-in length. This may readilybe accomplished, as by dividing the link, which has been referred togenerally bv the reference character 47, into several adjustableelements. As indicated in the drawings, the connection may consist of aro-d 47 screw threaded at its lupper end into a threaded socket 47bcarried by a short link 47c which is pivotally secured to the end of arm45, rod 47a extending at its lower end into a sleeve 50, in which it issecured against lengthwise movement relative thereto by a headed screwoperating in a groove'in the rod, or the like. The connection at thelower end may be similar, a rod 47d being secured against lengthwisemovement within sleeve' 50 and extending downwardly therefrom and beingscrew-threaded at its lower end into a nut 47 which is suitablyconnected to the roller 51 which coacts with cam 48. L j

The cup having been filled at the position d will now advance to theposition e and will be turned over to empty during the passage, and atthe same time will be rotated about its own axis as described. To

'accomplish these movements I have illustrated each cup holder as havinga spindle 52 extending downwardly. therefrom (Figs. 4 and 6) thisspindle being rotatably mounted in bearings 53 formed in a yoke 54 whichis rotatably mounted on a horizontal shaft 55. The latter is fixedlysecured as by means of set screw 56 to the bearingv 57 which is securedto the upper surface of table 3 adjacent the periphery thereof. Shaft 55carries at its outer end a beveled gear 58 which is lpinned or otherwisesecured thereto so as to be fixed in position.- The spindle 52 whichcarries holder 4 has a beveled pinion.

59 securedthereto to rotate therewith, this pinion constantly meshingwith beveled gear 58. y

Each of the yokes 54 has a. boss on which is secured a spur pinion 60,pinions 60 meshing with vertical racks 61,tliese racks being slidablymounted in suitable guideways 62 which are secured to,l or are integralwith, bearings 57 carried by table 3. Racks 61 are provided at theirlower ends with rollers 63 which are adapted to travel over the uppersurface of a cam track 64 which may extend circularly throughsubstantially onehalf a circle, immediately adjacent to the periphery oftable 3, cam track 64 being secured at its t'woends to the uppersurfaces f of channel members 2, extensions 65 of cam track 64'beingintegral with or secured to the end portions of cross member 10, securedto frame members 2 by bolts 11, as previously mentioned.

Rollers 63 are held down into contact with cam track 64 by mea-ns ofcompression springs G6 secured at their upper ends to table 3 and havingtheir lower ends engage brackets 67 secured to racks 61. During thepassage of a cup holder from the position al to the position c thecorresponding rack 61 will ride up cam track 64 from its lowest pointtoits highest point which results .in the rotation of pinion 60, yoke 54and the cup holder 4 through 1800, completely reversing the cup holderfrom the positiony shown in Fig. 4 to the position shown in Fig. 6.During the next advance of the machine in which the cup holder movesfrom position e to position f, the rack 61 referred to will ride down anincline of the cam track 64, from its highest point to its lowest pointso that the cup holder will be returned to its normal vertical positionwheniit reaches position 7. The cup holder will remain in this positionduring its passage from position f all the wa-y around to position dagain, during which time roller 63 will ride off of one end of the camtrack and will again ride on to the other end of the same, rack 61having a shoulder 68 at its upper end (Fig. 7),'which will rest on topof guide 62, to support the rack in its lowest position until the roller63 at the bottom of the same again rides on to the forward end of camtrack 64, adjacent to the position al. i

During the downward tilting of the cup holder, as described, while thecup holder travels from position d to position e, the cup holder and thecup contained therein will be given a desired rotation about the axis ofthe cup holder by the enga-gement of beveled pinion 59 with beveled gear58, the latter being stationary so that pinion 59 will rotate as ittravels over the same during the downward swinging of yoke 54. Thisrotation, as stated, may be one of a desired eX- tent such as fromone-half a revolution to one full revolution, during which time themolten parafline in the cup will flow towards the rim of the cup alonglines which are somewhat separated from' each other. The surplus liquid,thatis the liquid which does not stick to the inside of the cup, willrun out of the cup as the latter is reversed and fall into a drip pan 69which may extend beneath the path of the cup holder between positions dand e of the latter. In practice a comparatively small amount of moltenimpregnating material will be poured into each cup 5, such for exampleas an amount sufficient to filllthe cup from one-eighth to one-quarterfull.

Each cup as it arrives at position e will be ejected from the cup holderand this operation is preferably carried out automatically. One way ofaccomplishing this result is illustrated in-Figures 2 and 6 in which thecup holder is provided with a plunger 70 within the same and normallypositioned against the bottom of the cup holder. This plunger, which mayconstitute a metal disc or the like, is carried by a rod 71 whichextends through the spindle 52 on which the cup holder is mounted, theinner rod 71 extending through an opening in the bottom of the cupholder. At its opposite end the inner rod 71 extends beyond the oppositebearing 53 of yoke 54 and is provided at its end with an enlargement 72between which and the shoulder 53 of yoke 54 a spiral spring 7 3 iscoiled so as to normally hold the plunger disc 70 against the bottom ofthe cup holder.

Rod 71 is depressed, against the action of spring 73, when the cupholder arrives at the position indicated at e, by an arm 74 which ispivoted intermediate its ends at 75 to a bracket 76 which extendsupwardly from the horizontal frame of the machine, as is shown in F ig.2. One end of arm 74, as indicated at 77, normally rests upon or abovethe head 72 at the end of rod 71. A link 78 is connected to the oppositeend of arm 75 and extends downwardly, its lower end being connected, asis indicated at 79,- to onel end of a bell crank lever 80, which ispivoted at 81 to the frame of the machine. The opposite end of the bellcrank carries a roller 82 which is pressed by spring 83 into engagementwith the periphery of a cam wheel 84 mounted on shaft 7. This cam wheelis provided with a number of rises 85, which will be six in number inthe case of an apparatus having six spaced cup holders, as is shownherewith. The rises 85 of the cam are properly spaced so that bell crankwill be operated to depress its tappet 77 immediately after table 3 hascompleted each advance movement. This operation will result in plunger70 being depressed, as is indicated in dotted lines in Fig. 2, to ejectthe cup 5 which has arrived at theposition e upside down.

A travelling conveyor is provided for the purpose of carrying away thecups as they are ejected from the cup holders and carrying the samethrough a suitable oven. For this purpose l have illustrated a chain 86running over a sprocket wheel 87 at one end and a sprocket wheel 88 atthe other end.

' Sprocket wheel 87 is lcarried by brackets .89

extending downwardly from horizontal frame members 2. Sprocket wheel 88is carried by a shaft 90 which is driven by spur gears 91 and 92 fromshaft 20. Itshould be noted, referring to Fig. 5, that shafts 2O and 90may be supported from one of the channel frame members 2 by brackets 93,

one of which is shown in Fig. 5; each of these brackets carrying abearing for shaft 20 and also a bearing for shaft 90.

Chain 86 carries at properly spacedintervals supporting members 94 onwhich cups 5 will be received as they drop from the cup holders. Eachsupporting member 94 may comprise a metal rod which is secured to one ofthe links of the chain in any suitable manner, as is indicated at 95 inFig. 5, the member then extending horizontally for a distance afterwhich it is bent at right angles to extend upwardly, when it is on theupper level of the chain, or downwardly when the portion of the chain towhich it is secured is returning on the lower level, as shown at 96. Ahead 97 is provided at the end of the vertical portion 96 upon which thecup will rest, upside down, when it has dropped from the cup holder.Supports 94 should. of course, be so spaced on the chain and the advanceof the chain should be at such a rate that a support 94 will always bein position to receive a cup at the moment when the latter is ejectedfrom the cup holder at position e. The cup supports are preferablyoff-set from the chain, asindicated, so that there will be no possibiltyof molten paraiiine dripping from the cups on the chain. A drip pan 691will be provided to catch such drippings, this pan preferably `loeing acontinuation of the drip p an 69, previously referred to as extendingbeneath the travel of the cups from position d to position e.

The cups are carried by supports 94 through an oven or heating deviceindicated at 98. This may comprise a tunnel like cover heated by gasflames'issuing from perforations in pipes 99, 99, perforated shields 100preferably being mounted about the perforated gas pipes.

The passage of the cups through this oven will result in the spreadingofthe parafline or other impregnating material over the inner surface ofeach cup and the impregnation of the cup with the material in the mannerpreviously described. When the cups have been revolved about their ownaxes when the same are tilted downwardly, so as to cause the moltenmaterial to floJw in more or less spiral lines over the inner surface ofthe cup walls, the effect of the heat imparted as the cups pass throughoven 98 will be to cause the impregnating material to run downwardly invertical lines andl al^so spread by capillary attraction connectingtogether the various spiral lines referred to, the cups i being carriedthrough the oven upside down,

as stated. v

When ,the 'cups have passed through oven 98 they may be removed from thesupports on conveyor chain 86 by hand, or otherwise, and stacked, orconveyed to another point for cooling. I have not illustrated anyapparatus for carrying out such further steps as the same is not deemedessential.

After a cup has been ejected from the cu holder4 at the position ethevcup holder Wi l be returned to its normal upright position, ,duringthe further progress of table 3, as has previously been stated, by theaction of the rack 6l adjacent to that particular cup holder indescending the cam track 64 from its highest point to its lowest. y

It will be noted that the tilting and emptying of each cup arepreferably accomplished, by the mechanism described, in a comparativelyshort time, and that this occurs very shortly after the liquid is pouredinto the cup, so that surplus material will be removed before it has hadmuch opportunity to be absorbed by the material of the cup. Also, thatthe cup is preferably given a limited rotation only, about its own axis,during the tilting, which rotation may be, for example, as stated, fromone-half revolution to one revolution, so that, when a small amount ofliquid is poured in the cup, this liquid will travel spirally over.Vseparated portions only of the inner surface of the cup as the lat---ter is inverted.

It is believed that the operation of the device will be entirely clearfrom the above description. It should be understood that the inventionis not limited strictly to the details of construction which have beendescribed but that the invention is of considerable breadth as isindicated by the accompanying claims.
